Grajales-Nishimura et al. (2000) suggested that “offshore oil-producing breccias and seals from oil fields in the Campeche marine plateform are of K-T boundary age and that their mode of formation is probably related to the K-T impact event at Chicxulub.” The basis for this interpretation is the assumption that the siliciclastic deposits in Cretaceous-Tertiary (K-T) boundary sections in Texas, Alabama, and northeastern Mexico, and limestone breccia deposits in Cuba, the Campeche marine platform, and in southern Mexico (e.g., Guayal, Bochil) are impact ejecta-, megatsunami-, and debris flow deposits triggered by the Chicxulub impact. However, the stratigraphic ages of these deposits...
